Article Synopsis
  • Flow diverter devices are tiny stents designed to redirect blood flow away from brain aneurysms, helping to prevent their rupture by inducing blood clotting within the aneurysm.
  • Current options leave permanent materials in the body, which can lead to complications, making absorbable devices that dissolve after use a better choice.
  • The study introduces a new composite wire made of absorbable iron alloy and pure molybdenum, showing promising mechanical properties, progressive corrosion, and reduced fragmentation risk, indicating they could be ideal for absorbable flow diverters.

A new series of zinc alloys is in development for bioresorbable stent implantation to alleviate the current materials' long-term complications. Characterization and optimization of the microstructure and corresponding mechanical properties during manufacturing stages will help researchers meet the required values. In this study, the effect of hot extrusion on the Zn-Ag-Mn-Cu-Zr-Ti alloy is characterized.

The metallurgical engineering of bioresorbable zinc (Zn)-based medical alloys would greatly benefit from clarification of the relationships between material properties and biological responses. Here we investigate the biocompatibility of three Zn-based silver (Ag)-containing alloys, ranging from binary to quinary alloy systems. Selected binary and quinary Zn-Ag-based alloys underwent solution treatment (ST) to increase the solubility of Ag-rich phases within the Zn bulk matrix, yielding two different microstructures (one without ST and a different one with ST) with the same elemental composition.
